LUCY™ 3D QA PhantomEnd-to-End Stereotactic QA
One phantom for the full stereotactic QA chain — imaging, fusion, planning, dose delivery. Manufactured to 0.1 mm per-component tolerance so the phantom's own contribution to the end-to-end uncertainty budget stays near zero.
Key Features
- Every component manufactured within 0.1 mm tolerance (manufacturer specification)
- End-to-end stereotactic QA in a single phantom — imaging through dose delivery
- Interfaces with most commercial SRS frames and frameless systems
- Multiple targeting inserts for varying QA scenarios
- Dosimetry inserts for absolute, relative and point-dose measurements at isocentre

Applications
Every link in the SRS QA chain — one phantom
SRS / SRT end-to-end QA
Test every link in the stereotactic chain — imaging, fusion, planning, couch positioning, dose delivery — under patient-like conditions, with one phantom and one session.
MPPG 9.a compliance E2E
AAPM MPPG 9.a (Halvorsen 2017) requires "appropriate E2E phantoms for the scope of SRS-SBRT services offered, available for use on site in a timely manner (not to exceed 72 hr)." Lucy 3D is the fit.
Image fusion verification
Sub-millimetre inserts surface CT-to-MRI, CT-to-CBCT and CT-to-PET fusion errors before they affect a stereotactic plan.
MR distortion / geometric QA
The MR signal-generator and grid distortion insert (used in Sarkar 2016) characterise geometric distortion across the MRI field of view for MR-only or MR-guided planning.
Radiosurgery dose QA
A16-class micro chambers in dosimetry inserts give absolute and relative dose measurements at the SRS isocentre — small-field-appropriate.
Frameless SRT commissioning
Commission mask-based frameless SRT systems with known-geometry targets across the major frame and frameless interfaces.
Why LUCY 3D?
Stereotactic uncertainty is the sum of every link in the chain — imaging, fusion, plan, delivery. The 0.1 mm per-component manufacturing tolerance keeps the phantom's own contribution to that sum as low as the standards allow.
From CT acquisition to dose readout — imaging QA, fusion QA, mechanical QA and dose QA in a single workflow. The MPPG 9.a "72-hour E2E availability" requirement becomes a one-tool problem.
Lucy 3D was put head-to-head against StereoPHAN in a 2016 J Radiosurg SBRT study, using an A16 micro chamber on a Brainlab headframe with MR distortion inserts. The reference comparison is published; you can read it cold.

FAQ
End-to-end SRS / SBRT QA — questions we hear from Indian medical-physicist teams
Why daily linac QA isn't enough for a stereotactic programme, what LUCY 3D verifies that slab-and-film can't, which platforms it fits (CyberKnife, MR-linac, C-arm SRS), and how it anchors an MPPG 9.a commissioning report.
Q.Why does an SRS or SBRT programme need an end-to-end QA phantom on top of daily linac QA?
Daily linac QA verifies the machine at isocentre; the SRS / SBRT chain has many more places where sub-millimetre error accumulates — CT simulation, MRI-to-CT registration, TPS planning, image guidance, couch positioning and finally beam delivery. AAPM MPPG 9.a mandates a periodic end-to-end (E2E) test that drives one physical target through the entire chain and verifies the delivered dose lands where the plan intended. If the E2E test isn't run, a registration or targeting error can silently pass every stage and only surface on the treatment day.
Q.What does the LUCY 3D QA Phantom actually solve that a slab-and-film setup doesn't?
A slab-and-film setup verifies dose in one plane. The LUCY 3D presents a single spherical phantom that carries interchangeable inserts for CT imaging, MRI imaging, kV / MV imaging alignment, a targeting Winston-Lutz ball and a dosimetry film / OSL insert — all indexed against a machined 0.1 mm reference frame. The same physical phantom runs through the entire pathway and reveals the accumulated geometric error at the treatment couch, not the isolated planning-plane error.
Q.Is LUCY 3D compatible with CyberKnife, MR-linac and conventional C-arm SRS?
Yes. The phantom is treatment-platform agnostic — CyberKnife AQA (Automatic Quality Assurance), MR-linac E2E QA, TrueBeam / Radixact / Halcyon / Ethos SRS/SBRT, Elekta Versa HD SRS all read from the same phantom body. Sarkar 2016 (Journal of Radiosurgery & SBRT) is the peer-reviewed E2E validation across multiple platforms.
Q.How does LUCY 3D fit MPPG 9.a commissioning of a new SRS programme?
MPPG 9.a specifies E2E localisation ≤ 1 mm and dose delivery within 5 % for an SRS commissioning report. The LUCY 3D 0.1 mm manufacturing tolerance keeps the phantom itself well inside the measurement uncertainty budget, so any deviation caught at the phantom is attributable to the treatment chain — not to the phantom. Commissioning teams use the phantom to establish the E2E baseline that annual re-verification is measured against.
Q.How is LUCY 3D supplied and supported in India?
LUCY 3D QA Phantom is distributed across India by Saxsons Group under SKU RT-011. The package covers the phantom body, insert library (targeting, imaging, dosimetry), storage case and MPPG 9.a workflow-setup support — the department signs one PO and can stand up an E2E SRS/SBRT QA programme in the same commissioning cycle as the linac itself.
